LUBRICATING MIXTURE AND PROCESS OF MAKING SAME.

No Drawing.

My invention relates to improvements in lubricating mixtures, and the process of mak-. ing the same.

An objectof my invention is to provide a.

lubricating mixture which will obviate certain'of the disadvantages that attach to the mineral oils now in use. @110 of these disadvantages is that under certain conditions there is not the proper adhesion of the oil to the metal surface and this results in excessive wear because of. the fact that the'lubrieating fluid has not suflicient-ly covered the surface. My invention is designed to provide a lubricant which will adhere to the metaland which will cause the lubricant to coat it so that the friction is greatly reduced.

A further object of the invention is to provide a lubricating mixture which can be used in connection with internal combustion engines and which tends to seal the space between the piston rings and the cylinder so completely that gasoline is prevented from passing the piston and from diluting the oil in the crank-case.

A further object is to provide a process by means of which the lubricating mixture is prepared.

Other objects and advantages will appear in the following specification. and the novel features of the invention will be particularly pointed out in the appended claims.

In carrying out my invention, T make use of the inner mucilaginous bark of the U Imus fez-7m (slippery elm). This bark is ground or shredded when dry or partially. so and is enclosed in a bag of muslin or similar cloth and then is immersed in water, preferably kept at 80 F. and allowed to stand for six hours.

The bag with its water fluid contents is then lifted from the tank or receptacle in which it has been immersed and the surplus water is allowed to drain from it. The bag is afterwards put in a press and the liquid extract is forced out. The pressure is gauged so as not to press outany solids;

The expressed mucilaginous liquid is now mixed with a good mineral lubricating oil of a petroleum base of medium grade. The proportions are one part of the expressed mucilaginous liquid to five parts of the mineral lubricating oil. The mixture is now put into a mechanical mixer and is agitated -from five to fifteen minutes or until the mixture has the appearance of a smooth cream and is free from any small lumps and is of a homogeneous texture and of a uniform color.

Application filed February 7, 1927. Serial No. 166,588.

The mixture which is in the nature of an emulsion is now placed in a receptacle and allowed to stand for some time. pret'erahl 'v for twelve hours, during which time any 6 solids which may have been in the mixture have beenprecipitated and any uncmulsitied water will have also passed to the bottom.

The remaining portion of the mixture is decanted; that is to say. that portion above the sediment and water is drawn olf and this constitutes the lubricating emulsion which forms the subject of the present invent-ion. This emulsion I will call A. v

The emulsion A can now be mixed with any suitable mineral lubricating oil of a petroleum base in any desired proportions for use. I have found that good proportions for use are one partof the emulsion i-V to eightparts of oil for a light lubricant. one to seven for medium, and one to six for a heavy'lubricant.

1 In trying out this lubricant in practice I have found that it tends to seal the space between the piston rings and the cylinder wall in an internal combustion engine, thereby preventing thev flow of gasoline into the crank-case.

While I have spoken of the use of the mixture for internal combustion engines. it will be understood that any lubricating oil other than mineral oil of a petroleum base and hard grease may be prepared with mucilaginous liquid from the inner bark of the U l-m'us filled (slipper v elm). This latter oil and grease is treated in the same manner as the mineral oil of a petroleum base and in every instance the adhesion of the oil 'or grease to the part to be lubricated appears to be increased and thus the lubricating ctt'ect is increased since it holds the oil on the part to be lubricated or causes itto cling to the surface. thus greatly reducing wear, and. in the instance given above, forming a seal in the internal combustion engine for preventing the passage of gasoline.

I claim:

1. A lubricating emulsion. consisting of a mineral lubricating oil and an aqueous extract of the Ulmus fuZva in proportions of substantially five parts by volume of the oil and one part'by volume of the extract.

2. The herein described process of making a lubricating emulsion, which consists in mixing with a mineral lubricating oil an aqueous extract of the inner bark of the Ulmus fulra, permitting the mixture to settle, and separat- I ing thelighter fluid emulsion from the sedi- 7 mineral lubricating oil having its particles mtimately mixeclwlth particle's of an aqueous extract of the inner bark of'the Ulmus ful'va. 20

went and uneinulsified Water.

3. The herein described process of making a lubricating emulsion, which consists in mixing with a mmeral lubricating 011 an aqueous extract of the inner-bark of the U Zm us fuloa A lubricating emulsion, consisting of a mineral lubricating oil and an aqueous extract of the inner bark of the U Zmus f'ul'ua in volume of the oil and one part by volume in proportions of substantially five parts by proportions of substantially five parts by vol- 1 ume of the oil and one part by Volume of the 25 of the extract,'permitting the mixture to extract, and one'part by Volume'of the emulq settle, separating-the lighter fluid emulsion from the sediment and unemulsified Water,

and mixing with the emulsion a mineral lubricating 011 111 proportions of substantially one part by'volume of the extract and seven parts. by volume of the mineral lubricating oil. 1

4. A lubricating emulsion, consisting of a sion and seven parts by volume of-a mineral lubricating oil.

6. A lubricating emulsion, consisting of a mineral lubricating oil of a petroleum base 30 and an aqueous extract of the inner bark of slippery elm. v
